Oh, that wasn't clear from this report. If only python-zopeinterface was
being upgraded, I would expect the window for this race to be very small
(but still present). The window is very large, though, when upgrading from
8.10 to 9.04. Because so many packages are being upgraded at once, the
packages will stay unconfigured (and potentially non-functional) for a long
time.

I'm surprised this hasn't come up before (which means it probably has and
I'm not aware of it). There may be a standard pattern for dealing properly
with this. I suggest taking the question to <email address hidden>.
